This issue was disclosed as part of the IBM Java SDK updates in April 2019. Vulnerability Details CVEID: CVE-2019-2602 DESCRIPTION: An unspecified vulnerability in Oracle Java SE related to the Java SE, Java SE Embedded Libraries component could allow an unauthenticated attacker to cause a denial of service resulting in a high availability impact using unknown attack vectors. CVSS Base Score: 7.5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 159698 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) Affected Products and Versions Rational Collaborative Lifecycle Management 6.0 - 6.0.6.1 Rational Team Concert 6.0 - 6.0.6.1 Remediation/Fixes 1. If your product is deployed on WebSphere Application Server (WAS) and your deployment does not use an Eclipse based client nor the RM Browser plugin, then it is sufficient to continue using the existing version of your IBM Rational product, and only upgrade the JRE in the WAS server. 2. For the below remediations, if you have a WAS deployment, then WAS must also be remediated, in addition to performing your product upgrades. Follow instructions at Security Bulletin: Multiple Vulnerabilities in IBM(R) Java SDK affect WebSphere Application Server April 2019 CPU to get the WAS remediation. 3. If you are deploying the Rational products to a WAS Liberty or a Tomcat Server, you will need to follow the instructions below to upgrade the JRE, and then must also configure to complete the upgrade process: o Stop the server: Navigate to the Server directory in your Ratonal product installation path and run this script: server.shutdown o Navigate to the server directory in your Rational product installation path, open server.startup script using prefered text editor (e.g., Notepad for Windows or Vim Editor for Linux) and add one more option to the healthcenter parameter set: - Search parameter -Dcom.ibm.java.diagnostics.healthcenter.agent in server.startup script to find the line containing the health center parameter. NOTE: For some Rational Collaborative Lifecycle Management versions, -Dcom.ibm.java.diagnostics.healthcenter.agent parameter may not be found in the server.startup, in this case the update is not needed and you can start using your server. Windows: Comment out the line (where HEALTHCENTER_OPTS parameter located) by inserting "rem " at the beginning of the line: Before modification: set HEALTHCENTER_OPTS=-agentlib:healthcenter ... After modification: rem set HEALTHCENTER_OPTS=-agentlib:healthcenter ... Linux: Comment out the line (where HEALTHCENTER_OPTS parameter located) by inserting "# " at the beginning of the line: Before modification: export HEALTHCENTER_OPTS="-agentlib:healthcenter ... After modification: # export HEALTHCENTER_OPTS="-agentlib:healthcenter ... o Start the server. Navigate to the Server directory in your Rational product installation path and run this script: server.startup. STEPS TO APPLY THE REMEDIATION: 1. Optionally, upgrade your products to an Extended Maintenance Release version: 6.0.2, 6.0.6 or 6.0.6.1. 2. Optionally, apply the latest ifix for your installed version. 3. Obtain the latest Java JRE CPU update for the IBM Java SDK using the following information. o For the 6.0.6 and 6.0.6.1 release: JRE 7.1.4.45(<product> -JavaSE-JRE-7.1SR4FP45) or JRE 8.0.5.35(<product>-JavaSE-JRE-8.0SR5FP35) - Rational Collaborative Lifecycle Management 6.0.6.1 o For the 6.0.2 release: JRE 7.1.4.45(<product>-JavaSE-JRE-7.1SR4FP45) - Rational Collaborative Lifecycle Management 6.0.2 4. Upgrade your JRE following the instructions in the link below: How to update the IBM SDK for Java of IBM Rational products based on version 3.0.1.6 or later of IBM's Jazz technology 5. Navigate to the server directory in your Rational product installation path, and go to jre/lib/security path. 6. Optionally, If you have not performed a Licenses upgrade as described in the link below, please follow the instructions to complete the setup: No IBM Rational trial, server, or client access licenses available after upgrading Java and/or listed products Workarounds and Mitigations None Important Note IBM strongly suggests that all System z customers be subscribed to the System z Security Portal to receive the latest critical System z security and integrity service. If you are not subscribed, see the instructions on the System z Security web site. Security and integrity APARs and associated fixes will be posted to this portal. IBM suggests reviewing the CVSS scores and applying all security or integrity fixes as soon as possible to minimize any potential risk.
